SmCo Magnets - Samarium Cobalt Magnets

Material Information

  • An alloy compose of SmCo5/Sm2Co17 produce by powder metallurgical method
  • Extremely hard & brittle
  • High demagnetization resistance
  • Excellent anti-corrosion properties
  • More expensive than SmCo magnets because of limited raw material supply
  • Outstanding thermal stability
